Difference Between VPN and Firewall. In this article, you will read about what is VPN, what is firewall, what is the main difference between VPN and firewall, and a comparison between VPN vs Firewall. Both VPN and firewall are important for cybersecurity and provide protection to the computer but in two different ways.
Difference Between VPN And Firewall:
The main difference between VPN and firewall is that the VPN encrypts the traffic of our device, along with hiding our data from all other users. On the other hand, a Firewall prevents someone from establishing a connection with our device, if it is trying to access our network.
What Is VPN?
VPN stands for Virtual Private Network. VPN reroutes the internet traffic and hide the IP address. In VPN, the websites can’t see your location or original IP. VPN works on the operating system level. This means it reroutes all the coming traffic, whether it is from a browser or any background app. VPN encrypts the traffic between the internet and a device. It provides you with high online privacy and security. VPN protects you from website tracking, government surveillance and hacker that want to intercept your data or device.
The encryption done by VPN hides our data that no one can read, else the one who is using our network, the ISP and the government. VPN protect you from website tracking, government surveillance and hacker that want to intercept your data or device.
What Is Firewall?
A firewall protects your device when someone is establishing a connection and want to access your network. As the name firewall has the word wall in it, which means defence. It acts as a defensive barrier for our device and network. The firewall is responsible to verify each and every traffic that is coming to and from the network.
It informs us about the threats and harm that can affect our computer. We have to verify that whether that threat was true or not. You have seen that Computer Windows comes with pre-installed window firewall software. Whenever we install a new program on a computer, this firewall gives us a warning and wants our permission to install it or not.
